Using the module with high-speed counters
Please take note of the following information on the use of the module in
connection with high-speed counters:
Note
When connecting the 24 V power supply via a mechanical contact, the outputs of
the SM 323; DI 16/DO 16 x 24 VDC/0.5 A carry a “1” signal for approximately
50 s for reasons associated with the circuitry.
